Esmerald application running with a Scheduler

This serves as a simple application using Esmerald and running the default scheduler with some simple tasks as described in the documentation.

With some minor alterations for the frequency of the tasks for example purposes of course.

Requirements

  • Python 3.8+
  • A Python Virtual environment (optional) at your choice.

Installation

You will need to clone the repo.

$ git clone https://github.com/dymmond/scheduler-example

And then:

$ cd scheduler-example
$ pip install -r requirements/development.txt

Run the local

To run the project locally, after the installation, simply run:

$ esmerald runserver

Or alternatively

$ make run

There is a default API that you can access via http://localhost:8000/docs/swagger and play along but the most important thing is that you will be able to see in the console the default tasks running as per schedule.

Something like this:
